LUMBER- ELEVATOR.

$PECIPICAI'ION forming part of Letters Patent No. 300,119, dated June 10, 1884.

' Application filed 11.1 14, 1884. (x0 model.)

To aZZ whom it may concern.-

Be it known that I, JOHN PAUL, a citizen of the United States, residing at La Grosse, in the county of La Crosse and State of Wisconsin, have inv'nted certain new and useful Improvements in Lumber-Elevators, 'of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side view of a lumber-elevator with my improvements attached. Fig. 2 is a front elevation of the same. Fig. 3 is a side view of the sliding carriage.

My invention relates to means for elevating or hoisting lumber into piles in yards, on wharves, or other suitable places; and it consists in a carriage for holding the lumber, the said carriage being operated by suitable mechanism by an operator stationed on the ground and it further consists in the arrangement and combination of devices to be hereinafter more fully set forth, and specifically pointed out in the claims.

To enable others skilled in the art to make and use my invention, I will proceed to de-- scribe the exact manner in which I have carried it out.

In the said drawings, A represents the frame of the elevator, which is constructed, preferably, in the following manner: I take one board, a, for a base, which may be about sixteen inches wide and about twenty feet long, and on each side I bolt or otherwise secure a studding, b, one and one-half by three and one half inches. This studding, it willbe observed, forms the sides of the elevator, and also acts as a guide for the lumber in its ascent. Between the sides I), I secure, as shown at o 0, strips of hard wood, on which the lumber lies, the space between the strips 0 being reserved for the passage of a rope or chain, to be hereinafter referred to. Secured to each side of the frame and within easy reach of the ground is a bracket, 0, in the outer endof which is journaled ashaft on which is mounted a drum, D, provided with a suitable pawl-aud-ratchet mechanism for controlling the movement of the elevator, and on the end of the shaft on which the drum is mounted asuitable crank is attached. Around the drum D a cord or chain,

frame and passes over a sheave, h, mounted in the frame at its top, and thence passes downward in the space formed by the strips 0, secured to the base-board, when it connects with an eye formed on the upper portion of sliding carriage E, as shown in Fig. 3. This carriage is made of wood or light metal, provided at its bottom with an angular projection, a, to which is bolted'or otherwise secured a board or strip, 0, the outer end of which is a toe-piece, f, which holds the end of thelumher and prevents the same from slipping off during its ascent or descent.

The carriage is so constructed that it will hoist one or more pieces of lumber to within a short distan cc of the top of the elevator, so that, for example, a twenty-foot elevator will raise the upper end of a sixteen-foot board to a height of thirty-five feet, when the piler can readily remove it, the toe-piece f preventing the board from slipping off. Thus it will be seen that this device is especially'applicable in raising lumber to the top of high piles, which by the old manner is very difficult and dangerous.

To prevent the elevator from slipping, I se cure to the frame at its base and on each side suitable prongs, g.

The operation of my device is as follows: The pile of lumber having reached a height when it may be inconvenient to raise the lumber by hand, the elevator may be brought into use, the upper end resting against the pile. One or more pieces of the lumber to be piled is then placed in the frame with the ends resting between the toepiece and the frame. The operator on the ground turns the crank, which winds the rope or chain upon the drum, at the same time drawing the carriage and The piler at the top removes the lumber from the carriage, when the carriage, after being relieved of its load, will again descend by gravitation on releasing the pawl from the ratchet.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An elevator for hoisting lumber to the top of piles, consisting of an inclined frame with guide for the lumber, a sliding carriage F, is coiled, which passes upward beneath the operated by a rope or chain, and a toe-piece secured to thecarriage, substantially as here'- in set forth.

2. In an elevator for the purpose described, the frame A, provided with the side pieces,

I), and intermediate strips, 0, and a sheave, h,

mounted on the top of the frame, in combination with a sliding carriage constructed substantially as herein set forth, and themechanism, as described, for operating said carriage so as to elevate lumber beyond the top of the frame, substantially as and for the purpose set forth.

3. In an elevator for hoisting lumber to the top of piles, a carriage constructed substantially as shown, and adapted to slide in guides"
